NOTE: For those of you who are having problems with the left analog stick for Big Brother's movement, there's a fix for it posted at the Steam Community by a guy name Velve. Full credit goes to him for finding this fix.

Here's the fix: Go to your game folder then ../Engine/Config and open BaseInput.ini in notepad.Now look for this line:Bindings=(Name="XboxTypeS_LeftY",Command="Axis aBaseY Speed=1.0 DeadZone=0.3")And insert a "-" (minus sign) in front of the Speed value so that the line becomes:Bindings=(Name="XboxTypeS_LeftY",Command="Axis aBaseY Speed=-1.0 DeadZone=0.3")Save the file and start your game: you're done!

NOTE: For those who are having similar problems with the right analog stick (full credit goes to Heat for this fix) for Small Brother's movement, here's the fix for it;Just switch places of X and Y.
